2.3

Bringing the transmitter online
Transmitter User Interface

The DeviceNet cable used to connect the Model 2400S DN transmitter to the network provides both
power and communications. The transmitter is prewired with a male sealed Micro Connector
(Eurofast).
To bring the transmitter online:
1. Follow appropriate procedures to ensure that the process of configuring and commissioning
the Model 2400S DN transmitter does not interfere with existing measurement and control
loops.
2. Ensure that all transmitter and sensor covers and seals are closed.

WARNING
Operating the flowmeter without covers in place creates electrical hazards
that can cause death, injury, or property damage.

Configuration and Use Manual

Using ProLink II

To avoid electrical hazards, ensure that the transmitter housing cover and all other
covers are in place before connecting the transmitter to the network.

Flowmeter Startup

3. Insert an appropriate DeviceNet cable into the connector on the transmitter.
When the transmitter receives power, it will automatically perform diagnostic routines, and the
module LED flashes red and green. When the flowmeter has completed its power-up sequence,
the status LED will show a solid green. See Section 7.4 for information on LED behavior. If
the status LED exhibits different behavior, an alarm condition is present. See Section 7.5.
4. Ensure that the transmitter is visible on the network. For information on establishing
communications between the Model 2400S DN transmitter and a DeviceNet tool, see
Chapter 5.
Note: If this is the initial startup, or if power has been off long enough to allow components to reach
ambient temperature, the flowmeter is ready to receive process fluid approximately one minute after
power-up. However, it may take up to ten minutes for the electronics in the flowmeter to reach thermal
equilibrium. During this warm-up period, you may observe minor measurement instability or
inaccuracy.

Connecting to a Model 2400S DN transmitter
To connect to the Model 2400S DN transmitter using ProLink II or Pocket ProLink, you must use a
service port connection.
4.4.1

Connection options

The service port can be accessed via the service port clips or the IrDA port.
The service port clips have priority over the IrDA port:
•

If there is an active connection via the service port clips, access via the IrDA port is disabled.

•

If there is an active connection via the IrDA port and a connection attempt is made via the
service port clips, the IrDA connection is terminated.

Additionally, access via the IrDA port may be disabled altogether. In this case, it is not available for
connections at any time. By default, access via the IrDA port is disabled. See Section 8.10.6 for more
information.
4.4.2

Service port connection parameters

The service port uses default connection parameters. Both ProLink II and Pocket ProLink
automatically use these default parameters when Protocol is set to Service Port.
Additionally, to minimize configuration requirements, the service port employs an auto-detection
scheme when responding to connection requests. The service port will accept all connection requests
within the limits described in Table 4-1. If you are connecting to the service port from another tool,
ensure that configuration parameters are set within these limits.

Using a DeviceNet Tool

Chapter 5
Using a DeviceNet Tool

Overview
A customer-supplied DeviceNet tool can be used to communicate with the Model 2400S DN
transmitter. This chapter provides basic information on using a customer-supplied DeviceNet tool.

5.2

Connecting to the Model 2400S DN transmitter
To connect to the Model 2400S DN transmitter:
1. Default connection values for this transmitter are as follows:
•

DeviceNet node address = 63

•

Baud rate = 125 kBaud

Required Configuration

However, because there are a variety of DeviceNet tools available, this chapter does not provide
detailed information for using any one tool. For detailed information on your DeviceNet tool, see the
documentation supplied with the tool.

If required, use the digital communications hardware switches on the device to set the
DeviceNet node address and baud rate for this transmitter. To do this, see Sections 8.10.1 and
8.10.2.
Using the Transmitter

2. Connect to the network where the transmitter is installed.
3. Using the same methods that you use for other DeviceNet devices, establish a connection to
the Model 2400S DN transmitter, using the appropriate node address and baud rate.
5.3

Using the DeviceNet device profile
All DeviceNet devices employ a device profile with an object-instance-attribute structure.
In general, process and configuration data is stored in attributes, and operational functions are
performed by using services or setting attributes to specific values.
Two standard services are used to read or write single attributes:
The Get Single Attribute service (0x0E) performs an explicit read and returns a single value
from the transmitter.

•

The Set Single Attribute service (0x10) performs an explicit write and writes a single value to
the transmitter.

In this manual, these two services are referenced as the Get and Set services.
Other services are used to reset values to 0, start or stop calibrations, to acknowledge alarms, etc.
These services are identified by name and by service code (a hexadecimal label).
Input assemblies are used to publish multiple values to the DeviceNet bus. A summary of the input
assemblies is provided in Table 7-2. Output assemblies can be used to read data from the DeviceNet
bus or to perform totalizer and inventory control. Summaries of the output assemblies are provided in
Tables 7-9 and 9-1.
Configuration and Use Manual

Using a DeviceNet Tool

For complete documentation of the Model 2400S DN transmitter’s device profile, including input and
output assemblies, see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet:
Device Profile.
5.4

Using a DeviceNet tool
Micro Motion supplies an Electronic Data Sheet (EDS) for the Model 2400S transmitter. The EDS
file is named MMI2400S-MassFlow.eds. The EDS presents the device profile in a format designed to
be read and interpreted by other devices.
DeviceNet tools fall into two basic categories:
•

Type A: Tools that use the EDS to build a unique user interface for the specific device

•

Type B: Tools that do not use the EDS, and instead rely on the user to supply the
object-instance-attribute information required to interact with the device

5.4.1

Type A tools

If you are using a Type A tool:
1. Use your tool’s standard methods to read or import the supplied EDS into the network
configuration tool (e.g., RSLinx).
2. Use your tool’s standard user interface to configure, view, and manage the transmitter.
3. If you want to perform a function that isn’t available through your tool, see the instructions for
Type B tools.
5.4.2

Type B tools

If you are using a Type B tool, or if you want to access features that are not available through your
tool’s user interface, you must reference the feature by class, instance, and attribute, use the
appropriate service, and supply an attribute value if required. Depending on the attribute, the value
may be a numeric or character value or a code. Values must be entered in the data type appropriate to
the attribute.
For example:
•

To configure the mass flow cutoff, you must:
a. Specify the Analog Input Point class.
b. Specify the Mass Flow instance.
c. Specify the cutoff attribute.
d. Use the Set service to set the attribute value to the desired cutoff.

•

To read the mass flow process variable, you can use either of the following methods:
-

Use the Get service to read the value of the corresponding attribute.

Use one of the input assemblies that contains the mass flow process variable.

This manual provides class, instance, attribute, data type, and service information for most
configuration parameters and for all procedures. Complete documentation of the Model 2400S DN
transmitter’s device profile is provided in the manual entitled Micro Motion Model 2400S
Transmitters for DeviceNet: Device Profile.

Overview
This chapter describes the configuration procedures that are usually required when a transmitter is
installed for the first time.
The following procedures are discussed:
Characterizing the flowmeter – see Section 6.2

•

Configuring measurement units – see Section 6.3

This chapter provides basic flowcharts for each procedure. For more detailed flowcharts, see the
flowcharts for your communication tool, provided in the appendices to this manual.
For optional transmitter configuration parameters and procedures, see Chapter 8.
Note: All ProLink II procedures provided in this chapter assume that you have established
communication between ProLink II and the Model 2400S DN transmitter and that you are complying
with all applicable safety requirements. See Chapter 4 for more information.

•

Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter.

6.2

Characterizing the flowmeter
Characterizing the flowmeter adjusts the transmitter to compensate for the unique traits of the sensor
it is paired with. The characterization parameters, or calibration factors, describe the sensor’s
sensitivity to flow, density, and temperature.
6.2.1

Using the Transmitter

When to characterize

If the transmitter and sensor were ordered together, then the flowmeter has already been
characterized. You need to characterize the flowmeter only if the transmitter and sensor are being
paired together for the first time.
Characterization parameters

The characterization parameters that must be configured depend on your flowmeter’s sensor type:
“T-Series” or “Other” (also referred to as “Straight Tube” and “Curved Tube,” respectively), as listed
in Table 6-1. The “Other” category includes all Micro Motion sensors except T-Series.
The characterization parameters are provided on the sensor tag. See Figure 6-1 for illustrations of
sensor tags.

Flow calibration values
Two factors are used to define flow calibration:
•

The flow calibration factor, which is a 6-character string (five numbers and a decimal point)

•

The temperature coefficient for flow, which is a 4-character string (three numbers and a
decimal point)

These values are concatenated on the sensor tag, but different labels are used for different sensors. As
shown in Figure 6-1:

•

For T-Series sensors, the value is called the FCF value.

•

For other sensors, the value is called the Flow Cal value.

Micro Motion® Model 2400S Transmitters for DeviceNet™

•

With ProLink II, enter the concatenated 10-character string exactly as shown, including the
decimal points. For example, using the Flow Cal value from Figure 6-1, enter 19.0005.13.

•

With a DeviceNet tool, enter the two factors separately, i.e., enter a 6-character string and a
4-character string. Include the decimal point in both strings. For example, using the Flow Cal
value from Figure 6-1:

Configuring the measurement units
For each process variable, the transmitter must be configured to use the measurement unit appropriate
to your application.
To configure measurement units for process variables, see the menu flowcharts in Figure 6-3. For
details on measurement units for each process variable, see Sections 6.3.1 through 6.3.4.
The measurement units used for totalizers and inventories are assigned automatically, based on the
measurement unit configured for the corresponding process variable. For example, if kg/hr (kilograms
per hour) is configured for mass flow, the unit used for the mass flow totalizer and mass flow
inventory is kg (kilograms). DeviceNet codes used for the measurement units are listed in Tables C-12
through C-14.
Note: Pressure unit configuration is required only if you are using pressure compensation (see
Section 9.2) or you are using the Gas Wizard and you need to change the pressure units (see
Section 8.2).

Pressure units

The flowmeter does not measure pressure. You need to configure the pressure units if either of the
following is true:
•

You will configure pressure compensation (see Section 9.2). In this case, configure the
pressure unit to match the pressure unit used by the external pressure device.

•

You will use the Gas Wizard, you will enter a reference pressure value, and you need to change
the pressure unit to match the reference pressure value (see Section 8.2).

Required Configuration

If you do not know whether or not you will use pressure compensation or the Gas Wizard, you do not
need to configure a pressure unit at this time. You can always configure the pressure unit later.
The default pressure measurement unit is PSI. See Table 6-7 for a complete list of pressure
measurement units.

Micro Motion® Model 2400S Transmitters for DeviceNet™

7.1

Using a DeviceNet Tool

Chapter 7
Using the Transmitter

Overview
This chapter describes how to use the transmitter in everyday operation. The following topics and
procedures are discussed:
Recording process variables – see Section 7.2

•

Viewing process variables – see Section 7.3

•

Viewing transmitter status and alarms – see Section 7.5

•

Handling status alarms – see Section 7.6

•

Viewing and controlling the totalizers and inventories – see Section 7.7

Required Configuration

•

7.2

Recording process variables
Micro Motion suggests that you make a record of the process variables listed below, under normal
operating conditions. This will help you recognize when the process variables are unusually high or
low, and may help in fine-tuning transmitter configuration.
Record the following process variables:
Flow rate

•

Density

•

Temperature

•

Tube frequency

•

Pickoff voltage

•

Drive gain

Optional Configuration

•

To view these values, see Section 7.3. For information on using this information in troubleshooting,
see Section 11.13.

Configuration and Use Manual

Using the Transmitter

7.3

Viewing process variables
Process variables include measurements such as mass flow rate, volume flow rate, mass total, volume
total, temperature, and density.
You can view process variables with the display (if your transmitter has a display), ProLink II, or a
DeviceNet tool.
Note: If the petroleum measurement application is enabled, two of the API process variables are
averages: Batch Weighted Average Density and Batch Weighted Average Temperature. For both of
these, the averages are calculated for the current totalizer period, i.e., since the last reset of the API
volume totalizer.
7.3.1

With the display

By default, the display shows the mass flow rate, mass total, volume flow rate, volume total,
temperature, density, and drive gain. If desired, you can configure the display to show other process
variables. See Section 8.9.5.
The LCD panel reports the abbreviated name of the process variable (e.g., DENS for density), the
current value of that process variable, and the associated unit of measure (e.g., G/CM3). See
Appendix D for information on the codes and abbreviations used for display variables.
To view a process variable with the display:
•

If Auto Scroll is enabled, wait until the desired process variable appears on the LCD panel.

•

If Auto Scroll is not enabled, Scroll until the name of the desired process variable either:
-

Appears on the process variable line, or

Begins to alternate with the units of measure

See Figure 3-2.
The display precision can be configured separately for each process variable (see Section 8.9.5). This
affects only the value shown on the display, and does not affect the actual value as reported by the
transmitter via digital communications.
Process variable values are displayed using either standard decimal notation or exponential notation:
•

Values smaller than 100,000,000 are displayed in decimal notation (e.g., 1234567.89).

•

Values greater than 100,000,000 are displayed using exponential notation (e.g., 1.000E08).

7.3.2

If the value is less than the precision configured for that process variable, the value is
displayed as 0 (i.e., there is no exponential notation for fractional numbers).

If the value is too large to be displayed with the configured precision, the displayed
precision is reduced (i.e., the decimal point is shifted to the right) as required so that the
value can be displayed.
With ProLink II

The Process Variables window opens automatically when you first connect to the transmitter. This
window displays current values for the standard process variables (mass, volume, density,
temperature, external pressure, and external temperature).
To view the standard process variables with ProLink II, if you have closed the Process Variables
window, click ProLink > Process Variables.
To view API process variables (if the petroleum measurement application is enabled), click ProLink >
API Process Variables.

7.3.3

With a DeviceNet tool

There are two methods that can be used to view process variables with a DeviceNet tool:
You can execute Gets to read the current values of individual process variables from the
appropriate objects. Table 7-1 lists the most commonly used process variables, by class,
instance, attribute, and data type. For more information, see the manual entitled Micro Motion
Model 2400S Transmitters for DeviceNet: Device Profile.

•

You can use the predefined input assemblies. The predefined input assemblies are summarized

Handling status alarms
Specific process or flowmeter conditions cause status alarms. Each status alarm has an alarm code.

Using the Transmitter

•

Status alarms are classified into three severity levels: Fault, Information, and Ignore. Severity level
controls how the transmitter responds to the alarm condition.
Note: Some status alarms can be reclassified, i.e., configured for a different severity level. For
information on configuring severity level, see Section 8.8.

The transmitter maintains two status flags for each alarm:
•

The first status flag indicates “active” or “inactive.”

•

The second status flag indicates “acknowledged” or “unacknowledged.”

Configuration and Use Manual

Optional Configuration

Note: For detailed information on a specific status alarm, including possible causes and
troubleshooting suggestions, see Table 11-2. Before troubleshooting status alarms, first acknowledge
all alarms. This will remove inactive alarms from the list so that you can focus troubleshooting efforts
on active alarms.

Using the Transmitter

In addition, the transmitter maintains alarm history for the 50 most recent alarm occurrences. Alarm
history includes:
•

The alarm code

•

The “alarm active” timestamp

•

The “alarm inactive” timestamp

•

The “alarm acknowledged” timestamp

When the transmitter detects an alarm condition, it checks the severity level of the specific alarm and
performs the actions described in Table 7-6.

(2) See Sections 8.10.7 and 8.10.8 for more information on digital communications fault action and fault timeout.

When the transmitter detects that the alarm condition has cleared:
•

The first status flag is set to “inactive.”

•

Digital communications fault action is deactivated (Fault alarms only).

•

The “alarm inactive” record is written to alarm history (Fault and Informational alarms only).

•

The second status flag is not changed.

Operator action is required to return the second status flag to “acknowledged.” Alarm
acknowledgment is not necessary. If the alarm is acknowledged, the “alarm acknowledged” record is
written to alarm history.
7.6.1

Using the display

The display shows information only about active Fault or Informational alarms, based on alarm status
bits. Ignore alarms are filtered out, and you cannot access alarm history via the display.
To view or acknowledge alarms using the display menus, see the flowchart in Figure 7-1.
If the transmitter does not have a display, or if operator access to the alarm menu is disabled (see
Section 8.9.3), alarms can be viewed and acknowledged using ProLink II or a DeviceNet tool. Alarm
acknowledgment is not required.
Additionally, the display may be configured to enable or disable the Ack All function. If disabled, the
Ack All screen is not displayed and alarms must be acknowledged individually.

Ignore alarms are never listed.
You can acknowledge alarms from the Alarm Log window.
In the Alarm Log window:
•

The alarms are organized into two categories: High Priority and Low Priority. Each category is
displayed on a separate panel.

•

On a panel, a green LED indicates “inactive but unacknowledged” and a red LED indicates
“active.”

Note: The location of alarms on the Alarm Log panels is pre-defined, and is not affected by alarm
severity.

Using the totalizers and inventories
The totalizers keep track of the total amount of mass or volume measured by the transmitter over a
period of time.

You can view all totalizer and inventory values using any of the commmunication tools: the display,
ProLink II, or a DeviceNet tool. Specific starting, stopping, and resetting functionality depends on the
tool you are using.

Configuration and Use Manual

Optional Configuration

The inventories track the same values as the totalizers. Whenever totalizers are started or stopped, all
inventories (including the API volume inventory and enhanced density inventories) are started or
stopped automatically. However, when totalizers are reset, inventories are not reset automatically –
you must reset inventories separately. This allows you to use the inventories to keep running totals
across multiple totalizer resets.

Using the Transmitter

7.7.1

Viewing current values for totalizers and inventories

You can view current values for the totalizers and inventories with the display (if your transmitter has
a display), ProLink II, or a DeviceNet tool.
With the display
You cannot view current totalizer or inventory values with the display unless the display has been
configured to show them. See Section 8.9.5.
To view a totalizer or inventory value, refer to Figure 7-2 and:
1. Check for the word TOTAL in the lower left corner of the LCD panel.
•

If Auto Scroll is enabled, wait until the desired value appears on the LCD panel. You can
also Scroll until the desired value appears.

•

If Auto Scroll is not enabled, Scroll until the desired value appears.

2. Check the unit of measure to identify the process variable being displayed (e.g., mass, liquid
volume, gas standard volume).
3. Check the unit of measure line to determine whether you are viewing a totalizer value or an
inventory value:
•

Totalizer value: the unit of measure is a steady display.

•

Inventory value: the unit of measure alternates with one of the following:
-

MASSI (for Mass Inventory)

LVOLI (for Liquid Volume Inventory)

GSV I (for Gas Standard Volume Inventory)

TCORI (for API Temperature Corrected Inventory)

STDVI (for ED Standard Volume Inventory)

NETVI (for ED Net Volume Inventory)

Configuring volume flow measurement for gas
Two types of volume flow measurement are available:

•

Liquid volume (the default)

•

Gas standard volume

Micro Motion® Model 2400S Transmitters for DeviceNet™

Optional Configuration

Using a DeviceNet Tool

Only one type of volume flow measurement can be performed at a time (i.e., if liquid volume flow
measurement is enabled, gas standard volume flow measurement is disabled, and vice versa).
Different sets of volume flow measurement units are available, depending on which type of volume
flow measurement is enabled (see Tables 6-3 and 6-4). If you will use a gas standard volume flow
unit, additional configuration is required.
Note: If you will use the petroleum measurement application or the enhanced density application,
liquid volume flow measurement is required.
The method used to configure volume flow measurement for gas depends on the tool you are using:
ProLink II or a DeviceNet tool.
Note: For complete configuration of volume flow measurement for gas, you must use either ProLink II
or a DeviceNet tool. Using the display, you can only select a volume measurement unit from the set
available for the configured volume flow type.
Using ProLink II

To configure volume flow measurement for gas using ProLink II:
1. Click ProLink > Configure > Flow.
2. Set Vol Flow Type to Std Gas Volume.
3. Select the measurement unit you want to use from the Std Gas Vol Flow Units dropdown list.
The default is SCFM.

Required Configuration

8.2.1

4. Configure the Std Gas Vol Flow Cutoff (see Section 8.3). The default is 0.
5. If you know the standard density of the gas that you are measuring, enter it in the Std Gas
Density field. If you do not know the standard density, you can use the Gas Wizard. See the
following section.
Note: The term “standard density” refers to the density of the gas at reference conditions.
Using the Transmitter

Using the Gas Wizard
The Gas Wizard is used to calculate the standard density of the gas that you are measuring.
To use the Gas Wizard:
1. Click ProLink > Configure > Flow.
2. Click the Gas Wizard button.
3. If your gas is listed in the Choose Gas dropdown list:
a. Enable the Choose Gas radio button.
b. Select your gas.
4. If your gas is not listed, you must describe its properties.
a. Enable the Enter Other Gas Property radio button.

c. Provide the required information. Note that if you selected Density, you must enter the
value in the configured density units and you must provide the temperature and pressure at
which the density value was determined.
Note: Ensure that the values you enter are correct, and that fluid composition is stable. If either of
these conditions is not met, gas flow measurement accuracy will be degraded.

Configuration and Use Manual

Optional Configuration

b. Enable the method that you will use to describe its properties: Molecular Weight,
Specific Gravity Compared to Air, or Density.

Optional Configuration

5. Click Next.
6. Verify the reference temperature and reference pressure. If these are not appropriate for your
application, click the Change Reference Conditions button and enter new values for
reference temperature and reference pressure.
7. Click Next. The calculated standard density value is displayed.
•

If the value is correct, click Finish. The value will be written to transmitter configuration.

Configuring cutoffs
Cutoffs are user-defined values below which the transmitter reports a value of zero for the specified
process variable. Cutoffs can be set for mass flow, liquid volume flow, gas standard volume flow, and
density.
See Table 8-2 for cutoff default values and related information. See Section 8.3.1 for information on
how the cutoffs interact with other transmitter measurements.

•

Using a DeviceNet tool, see Tables C-1, C-2, C-3, and C-5.

8.3.1

Cutoffs and volume flow

If you are using liquid volume flow measurement:
•

The density cutoff is applied to the volume flow calculation. Accordingly, if the density drops
below its configured cutoff value, the volume flow rate will go to zero.

•

The mass flow cutoff is not applied to the volume flow calculation. Even if the mass flow
drops below the cutoff, and therefore the mass flow indicators go to zero, the volume flow rate
will be calculated from the actual mass flow process variable.

Required Configuration

Note: This functionality is not available via the display menus.

If you are using gas standard volume flow measurement, neither the mass flow cutoff nor the density
cutoff is applied to the volume flow calculation.
Configuring the damping values
A damping value is a period of time, in seconds, over which the process variable value will change to
reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small,
rapid measurement fluctuations.
•

A high damping value makes the output appear to be smoother because the output must change
slowly.

•

A low damping value makes the output appear to be more erratic because the output changes
more quickly.

Using the Transmitter

8.4

Damping can be configured for flow, density, and temperature.
When you change the damping value, the specified value is automatically rounded down to the nearest
valid damping value. Valid damping values are listed in Table 8-3.
Note: For gas applications, Micro Motion recommends a minimum flow damping value of 2.56.
Optional Configuration

Before setting the damping values, review Section 8.4.1 for information on how the damping values
affect other transmitter measurements.

8.4.1

Damping and volume measurement

When configuring damping values, note the following:
•

Liquid volume flow is derived from mass and density measurements; therefore, any damping
applied to mass flow and density will affect liquid volume measurement.

•

Gas standard volume flow is derived from mass flow measurement, but not from density
measurement. Therefore, only damping applied to mass flow will affect gas standard volume
measurement.

Be sure to set damping values accordingly.
8.5

Configuring the flow direction parameter
The flow direction parameter controls how the transmitter reports flow rate and how flow is added to
or subtracted from the totalizers, under conditions of forward flow, reverse flow, or zero flow.
•

Forward (positive) flow moves in the direction of the arrow on the sensor.

•

Reverse (negative) flow moves in the direction opposite of the arrow on the sensor.

Options for flow direction include:
•

Forward only

•

Reverse only

•

Absolute value

•

Bidirectional

•

Negate/Forward only

Configuring events
An event occurs if the real-time value of a user-specified process variable varies above or below a
user-specified value, or inside or outside a user-specified range. You can configure up to five events.
You may optionally specify one or more actions that will occur if the event occurs. For example, if
Event 1 occurs, you may specify that the transmitter will stop all totalizers and inventories and reset
the mass totalizer.
8.6.1

Defining events
Optional Configuration

To define an event:
•

Using ProLink II, see Figure B-3.

•

Using a DeviceNet tool, event specifications reside in the Diagnostics Object (0x66),
Instance 1. See Table C-7.

The following general steps are required:
1. Select the event to define (Attribute 6).
2. Specify the event type (Attribute 7). Event Type options are defined in Table 8-5.

Configuration and Use Manual

Optional Configuration

3. Assign a process variable to the event (Attribute 10).
4. Specify the event’s setpoint(s) – the value(s) at which the event will occur or switch state (ON
to OFF, or vice versa).
•

If Event Type is High or Low, only Setpoint A is used (Attribute 8)

•

If Event Type is In Range or Out of Range, both Setpoint A and Setpoint B (Attributes 9
and 10) are required.

5. Assign the event to an action or actions, if desired. Possible actions are listed in Table 8-6. To
do this:
•

Using ProLink II, open the Discrete Input panel in the Configuration window, identify the
action to be performed, then specify the event using the dropdown list. See Figure B-3.

Note: For consistency with other Micro Motion products, the Discrete Input panel is used here even
though the Model 2400S DN transmitter does not provide a discrete input.

Checking and reporting event status

There are several ways that event status can be determined:
•

ProLink II automatically displays event information on the Informational panel of the Status
window.

•

The status of each event is stored in the Diagnostics Object (0x66), Instance 1, Attribute 11.
For more information, see Table C-7, or see the manual entitled Micro Motion Model 2400S
Transmitters for DeviceNet: Device Profile.

8.6.3

Changing event setpoints from the display

For Event 1 or Event 2 only, the value of Setpoint A can be changed from the display, under the
following circumstances:
•

Mass total or volume total (gas or liquid) must be assigned to the event.

•

The event type must be either High or Low.

•

Mass total or volume total must be configured as a display variable (see Section 8.9.5).

Then, to reset Setpoint A from the display:
1. Referring to the totalizer management flowchart in Figure 7-3, Scroll to the appropriate
display screen:
•

To reset the setpoint for an event defined on mass total, Scroll to the mass total screen.

•

To reset the setpoint for an event defined on volume total, Scroll to the volume total
screen.

2. Select.
3. Enter the new setpoint value. See Section 3.5.5 for instructions on entering floating-point
values with the display.
8.7

Configuring slug flow limits and duration
Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in some applications.
The presence of slugs can significantly affect the process density reading. The slug flow parameters
can help the transmitter suppress extreme changes in process variables, and can also be used to
identify process conditions that require correction.
Slug flow parameters are as follows:

•

Slug flow low limit – the point below which a condition of slug flow will exist. Typically, this
is the lowest density point in your process’s normal density range. Default value is 0.0 g/cm3;
range is 0.0–10.0 g/cm3.

•

Slug flow high limit – the point above which a condition of slug flow will exist. Typically, this
is the highest density point in your process’s normal density range. Default value is 5.0 g/cm3;
range is 0.0–10.0 g/cm3.

•

Slug flow duration – the number of seconds the transmitter waits for a slug flow condition
(outside the slug flow limits) to return to normal (inside the slug flow limits). Default value is
0.0 sec; range is 0.0–60.0 sec.

Micro Motion® Model 2400S Transmitters for DeviceNet™

Optional Configuration

•

A slug flow alarm is posted immediately.

•

During the slug duration period, the transmitter holds the mass flow rate at the last measured
pre-slug value, independent of the mass flow rate measured by the sensor. The reported mass
flow value is set to this value, and all internal calculations that include mass flow rate will use
this value.

•

If slugs are still present after the slug duration period expires, the transmitter forces the mass
flow rate to 0, independent of the mass flow rate measured by the sensor. Mass flow rate is
reported as 0 and all internal calculations that include mass flow rate will use 0.

•

When process density returns to a value within the slug flow limits, the slug flow alarm is
cleared and the mass flow rate reverts to the actual measured value.

Using a DeviceNet Tool

If the transmitter detects slug flow:

To configure slug flow parameters:
Using ProLink II, use the Density panel in the Configuration window. See Figure B-2.

•

Using a DeviceNet tool, set Attributes 3, 4, and 5 in the Diagnostics Object (0x66), Instance 1.
See Table C-7.

Note: This functionality is not available via the display menus.
Note: The slug flow limits must be entered in g/cm3, even if another unit has been configured for
density. Slug flow duration is entered in seconds.
Note: Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility
of slug flow conditions. Conversely, lowering the low slug flow limit or raising the high slug flow limit
will decrease the possibility of slug flow conditions.

Required Configuration

•

Note: If slug flow duration is set to 0, the mass flow rate will be forced to 0 as soon as slug flow is
detected.
Configuring status alarm severity

Using the Transmitter

8.8

The Model 2400S transmitter can report faults in the following ways:
•

Setting the “alarm active” status bit

•

Writing an “alarm active” record to alarm history

•

Implementing the digital communications fault action (see Section 8.10.7)

Status alarm severity determines which methods the transmitter will use when a specific alarm

8.10.1

DeviceNet node address

The default node address for the Model 2400S DN transmitter is 63. The valid range of node
addresses is 0–63.
The DeviceNet node address can be set using digital communications hardware switches or a
DeviceNet tool.
Note: You cannot set the node address from ProLink II or the display.
To set the node address using digital communications hardware switches:
1. Remove the transmitter housing cover as described in Section 3.3.
2. Identify the two addresses switches (the left and center switches) on the user interface module
of your transmitter (see Section 3.3). The left switch, labeled MSD (Most Significant Digit),
sets the first digit of the node address, and the center switch, labeled LSD (Least Significant
Digit), sets the second digit.
3. For each switch, insert a small blade into the slot to rotate the arrow to the desired position. For
example, to set the node address to 60:
a. Rotate the arrow in the left switch to point to the digit 6.
b. Rotate the arrow in the center switch to point to the digit 0.
4. Replace the transmitter housing cover.
5. Either power cycle the transmitter or send a Reset service (0x05) to the Identity Object (0x01),
Instance 1.
Note: The new node address is not implemented until Step 5 is completed.
To set the node address using a DeviceNet tool:
1. Use the digital communications hardware switches to set the node address to any value in the
Program range (values 64–99). This essentially disables the digital communications hardware
switches and allows external control of the node address.
2. Set the MAC ID in the DeviceNet Object (0x03), Instance 1, Attribute 1, data type USINT.
3. Either power cycle the transmitter or send a Reset service (0x05) to the Identity Object (0x01),
Instance 1.
Note: If the digital communications hardware switches are not set to 64 or greater, the Set service will
return the error code 0x0E (Attribute Not Settable).
Note: The new node address is not implemented until Step 3 is completed.

Note: The new baud rate is not implemented until Step 5 is completed.
To set the baud rate using a DeviceNet tool:
1. Use the digital communications hardware switch to set the baud rate to any value in the
Program range (values 3–9). This essentially disables the digital communications hardware
switch and allows external control of the baud rate.
2. Set the baud rate in the DeviceNet Object (0x03), Instance 1, Attribute 2, data type USINT.
Note: If the baud rate digital communications hardware switch is not in the Program range, the Set
service will return the error code 0x0E (Attribute Not Settable).
3. Either power cycle the transmitter or send a Reset service (0x05) to the Identity Object (0x01),

Modbus address

Note: The Modbus address is applicable only when you are connecting to the service port from a tool
that uses Modbus protocol. After initial startup, service port connections are typically used only for
troubleshooting or for specific procedures such as temperature calibration. ProLink II is typically
used for service port connections, and by default ProLink II will use the standard service port address
rather than the configured Modbus address. See Section 4.4 for more information.
The set of valid Modbus addresses depends on whether or not support for Modbus ASCII is enabled
or disabled (see Section 8.10.5). Valid Modbus addresses are as follows:
•

Modbus ASCII enabled: 1–15, 32–47, 64–79, 96–110

•

Modbus ASCII disabled: 0–127

To configure the Modbus address:
•

Using ProLink II, see Figure B-2.

•

Using the display menus, see Figure B-6.

8.10.5

Modbus ASCII support

When support for Modbus ASCII is enabled, the service port can accept connection requests that use
either Modbus ASCII or Modbus RTU. When support for Modbus ASCII is disabled, the service port
cannot accept connection requests that use Modbus ASCII. Only Modbus RTU connections are
accepted.

Using a DeviceNet tool, see Table C-7.

Note: This functionality is not available via the display menus.
8.10.8

Fault timeout

By default, the transmitter activates the digital communications fault action as soon as the fault is
detected. The fault timeout allows you to delay the digital communications fault action for a specified
interval, for certain faults only. During the fault timeout period, digital communications behaves
normally.
Note: The fault timeout applies only to the digital communications fault action. The “alarm active”
status bit is set as soon as the fault is detected (all alarm severity levels), and the “alarm active”
record is written to history immediately (Fault and Informational alarms only). For more information
on alarm handling, see Section 7.6. For more information on alarm severity, see Section 8.8.
The fault timeout applies only to specific faults. Other faults are reported immediately, regardless of
the fault timeout setting. For information on which faults are affected by the fault timeout, see
Table 8-8.
To configure fault timeout:
•

Using ProLink II, see Figure B-2.

About the petroleum measurement application

Terms and definitions
The following terms and definitions are relevant to the petroleum measurement application:
•

API – American Petroleum Institute

•

CTL – Correction of Temperature on volume of Liquids. The CTL value is used to calculate
the VCF value

•

TEC – Thermal Expansion Coefficient

•

VCF – Volume Correction Factor. The correction factor to be applied to volume process
variables. VCF can be calculated after CTL is derived

Using the Transmitter

Some applications that measure liquid volume flow or liquid density are particularly sensitive to
temperature factors, and must comply with American Petroleum Institute (API) standards for
measurement. The petroleum measurement enables Correction of Temperature on volume of Liquids,
or CTL.

CTL derivation methods
Optional Configuration

There are two derivation methods for CTL:
•

Method 1 is based on observed density and observed temperature.

•

Method 2 is based on a user-supplied reference density (or thermal expansion coefficient, in
some cases) and observed temperature.

Configuration and Use Manual

Optional Configuration

API reference tables
Reference tables are organized by reference temperature, CTL derivation method, liquid type, and
density unit. The table selected here controls all the remaining options.
•

•

Reference temperature:
-

If you specify a 5x, 6x, 23x, or 24x table, the default reference temperature is 60 °F, and
cannot be changed.

If you specify a 53x or 54x table, the default reference temperature is 15 °C. However, you
can change the reference temperature, as recommended in some locations (for example, to
14.0 or 14.5 °C).

CTL derivation method:
-

If you specify an odd-numbered table (5, 23, or 53), CTL will be derived using method 1
described above.

If you specify an even-numbered table (6, 24, or 54), CTL will be derived using method 2
described above.

The letters A, B, C, or D that are used to terminate table names define the type of liquid that the
table is designed for:
-

A tables are used with generalized crude and JP4 applications.

B tables are used with generalized products.

C tables are used with liquids with a constant base density or known thermal expansion
coefficient.

D tables are used with lubricating oils.

Different tables use different density units:

Configuring the enhanced density application
Micro Motion sensors provide direct measurements of density, but not of concentration. The enhanced
density application calculates enhanced density process variables, such as concentration or density at
reference temperature, from density process data, appropriately corrected for temperature.
Note: For a detailed description of the enhanced density application, see the manual entitled
Micro Motion Enhanced Density Application: Theory, Configuration, and Use.
Note: The enhanced density application requires liquid volume measurement units. If you plan to use
enhanced density process variables, ensure that liquid volume flow measurement is specified. See
Section 8.2.
8.14.1

About the enhanced density application

The enhanced density calculation calculation requires an enhanced density curve, which specifies the
relationship between temperature, concentration, and density for the process fluid being measured.
Micro Motion supplies a set of six standard enhanced density curves (see Table 8-16). If none of these
curves is appropriate for your process fluid, you can configure a custom curve or purchase a custom
curve from Micro Motion.
The derived variable, specified during configuration, controls the type of concentration measurement
that will be produced. Each derived variable allows the calculation of a subset of enhanced density
process variables (see Table 8-17). The available enhanced density process variables can be used in
process control, just as mass flow rate, volume flow rate, and other process variables are used. For
example, an event can be defined on an enhanced density process variable.
•

For all standard curves, the derived variable is Mass Conc (Dens).

•

For custom curves, the derived variable may be any of the variables listed in Table 8-17.

The transmitter can hold up to six curves at any given time, but only one curve can be active (used for
measurement) at a time. All curves that are in transmitter memory must use the same derived variable.

Pressure Compensation
and Temperature Compensation

Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter.
Note: All DeviceNet tool procedures provided in this chapter assume that you have established
communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are
complying with all applicable safety requirements. See Chapter 5 for more information.
Pressure compensation
The Model 2400S DN transmitter can compensate for the effect of pressure on the sensor flow tubes.
Pressure effect is defined as the change in sensor flow and density sensitivity due to process pressure
change away from calibration pressure.

Troubleshooting

9.2

Note: Pressure compensation is an optional procedure. Perform this procedure only if required by
your application.
9.2.1

Options

There are two ways to configure pressure compensation:
If the operating pressure is a known static value, you can configure that value in the
transmitter.

•

If the operating pressure varies significantly, you must write a pressure value to the transmitter
at appropriate intervals, using an appropriate output assembly. See Section 9.4.

Note: Ensure that your pressure value is accurate, or that your pressure measurement device is
accurate and reliable.

Pressure Compensation and Temperature Compensation

9.2.2

Pressure correction factors

When configuring pressure compensation, you must provide the flow calibration pressure – the
pressure at which the flowmeter was calibrated (which therefore defines the pressure at which there
will be no effect on the calibration factor). Enter 20 PSI unless the calibration document for your
sensor indicates a different calibration pressure.
Two additional pressure correction factors may be configured: one for flow and one for density. These
are defined as follows:
•

Flow factor – the percent change in the flow rate per psi

•

Density factor – the change in fluid density, in g/cm3/psi

Not all sensors or applications require pressure correction factors. For the pressure correction values
to be used, obtain the pressure effect values from the product data sheet for your sensor, then reverse
the signs (e.g., if the pressure effect is 0.000004, enter a pressure correction factor of –0.000004).

These three procedures are discussed and compared in Sections 10.2.1 through 10.2.4. Before
performing any of these procedures, review these sections to ensure that you will be performing the
appropriate procedure for your purposes.

Measurement Performance

10.2.1

Meter verification

Meter verification evaluates the structural integrity of the sensor tubes by comparing current tube
stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit deflection, or
force divided by displacement. Because a change in structural integrity changes the sensor’s response
to mass and density, this value can be used as an indicator of measurement performance. Changes in
tube stiffness are typically caused by erosion, corrosion, or tube damage.
Meter verification does not affect measurement in any way. Micro Motion recommends performing
meter verification at regular intervals.
10.2.2

Meter validation and meter factors

Meter validation compares a measurement value reported by the transmitter with an external
measurement standard. Meter validation requires one data point.
Note: For meter validation to be useful, the external measurement standard must be more accurate
than the sensor. See the sensor’s product data sheet for its accuracy specification.
If the transmitter’s mass flow, volume flow, or density measurement is significantly different from the
external measurement standard, you may want to adjust the corresponding meter factor. A meter
factor is the value by which the transmitter multiplies the process variable value. The default meter
factors are 1.0, resulting in no difference between the data retrieved from the sensor and the data
reported externally.
Meter factors are typically used for proving the flowmeter against a weights and measures standard.
You may need to calculate and adjust meter factors periodically to comply with regulations.
10.2.3

Calibration

The flowmeter measures process variables based on fixed points of reference. Calibration adjusts
those points of reference. Three types of calibration can be performed:
•

Zero, or no flow

•

Density calibration

•

Temperature calibration

Density and temperature calibration require two data points (low and high) and an external
measurement for each. Zero calibration requires one data point. Calibration produces a change in the
offset and/or the slope of the line that represents the relationship between the actual process value and
the reported value.
Note: For density or temperature calibration to be useful, the external measurements must be
accurate.
Micro Motion flowmeters with the Model 2400S transmitter are calibrated at the factory, and
normally do not need to be calibrated in the field. Calibrate the flowmeter only if you must do so to
meet regulatory requirements. Contact Micro Motion before calibrating your flowmeter.
Note: Micro Motion recommends using meter validation and meter factors, rather than calibration, to
prove the meter against a regulatory standard or to correct measurement error.

10.2.4

Comparison and recommendations

•

Meter verification requires approximately four minutes to perform. During these four
minutes, flow can continue (provided sufficient stability is maintained); however, current
process data will not be reported.

Meter validation for density does not interrupt the process. However, meter validation for
mass flow or volume flow requires process down-time for the length of the test.

Calibration requires process down-time. In addition, density and temperature calibration
require replacing the process fluid with low-density and high density fluids, or
low-temperature and high-temperature fluids. Zero calibration requires stopping flow
through the sensor.

External measurement requirements
-

Meter verification does not require external measurements.

Zero calibration does not require external measurements.

Density calibration, temperature calibration, and meter validation require external
measurements. For good results, the external measurement must be highly accurate.

Measurement adjustment
Meter verification is an indicator of sensor condition, but does not change flowmeter
internal measurement in any way.

Meter validation does not change flowmeter internal measurement in any way. If you
decide to adjust a meter factor as a result of a meter validation procedure, only the reported
measurement is changed – the base measurement is not changed. You can always reverse
the change by returning the meter factor to its previous value.

Calibration changes the transmitter’s interpretation of process data, and accordingly
changes the base measurement. If you perform a zero calibration, you can return to the
previous zero or the factory zero. However, if you perform a density calibration or a
temperature calibration, you cannot return to the previous calibration factors unless you
have manually recorded them.

Troubleshooting

Micro Motion recommends that you purchase the meter verification option and perform meter
verification frequently.

Measurement Performance

•

Process interruption

Compensation

When choosing among meter verification, meter validation, and calibration, consider the following
factors:

Performing meter verification
The meter verification procedure can be performed on any process fluid. It is not necessary to match
factory conditions. Meter verification is not affected by any parameters configured for flow, density,
or temperature.
During the test, process conditions must be stable. To maximize stability:
Maintain a constant temperature and pressure.

•

Avoid changes to fluid composition (e.g., two-phase flow, settling, etc.).

•

Maintain a constant flow. For higher test certainty, stop flow.

Defaults

•

If stability varies outside test limits, the meter verification procedure will be aborted. Verify the
stability of the process and retry the test.

Configuration and Use Manual

Measurement Performance

During meter verification, you can choose between setting digital communications process variable
values to the configured fault indicator or the last measured value. The values will remain fixed for
the duration of the test (approximately four minutes). Disable all control loops for the duration of the
procedure, and ensure that any data reported during this period is handled appropriately.

10.3.1

Uncertainty limit and test results

The result of the meter verification test will be a percent uncertainty of normalized tube stiffness. The
default limit for this uncertainty is ±4.0%. This limit is stored in the transmitter, and can be changed
with ProLink II or a DeviceNet tool when optional test parameters are entered. For most installations,
it is advisable to leave the uncertainty limit at the default value.
When the test is completed, the result will be reported as Pass, Fail/Caution (depending on the tool
you are using), or Abort:
•

Pass – The test result is within the specified uncertainty limit. If transmitter zero and
configuration match factory values, the sensor will meet factory specifications for flow and
density measurement. It is expected that the meter will pass meter verification every time the
test is run.

•

Fail/Caution – The test result is not within the specified uncertainty limit. Micro Motion
recommends that you immediately re-run the meter verification test. If the meter passes the
second test, the first Fail/Caution result can be ignored. If the meter fails the second test, the
flow tubes may be damaged. Use the knowledge of your process to consider the type of
damage and determine the appropriate action. These actions might include removing the meter
from service and physically inspecting the tubes. At minimum, you should perform a flow
validation (see Section 10.4) and a density calibration (see Section 10.6).

•

Abort – A problem occurred with the meter verification test (e.g., process instability). Check
your process and retry the test.

ProLink II provides more detailed test data. See Section 10.3.2.

Additional ProLink II tools for meter verification

•

Visibility of configuration and zero changes – ProLink II has a pair of indicators that show
whether the transmitter’s configuration or zero has changed since the last meter verification
test. The indicators will be green if configuration and zero are the same, and red otherwise.
You can find out more information about changes to configuration and zero by clicking the
button next to each indicator.

•

Plotted data points – ProLink II shows the exact stiffness uncertainty on a graph. This allows
you to see not only whether the meter is operating within specification, but also where the
results fall within the specified limits. (The results are shown as two data points: Inlet and
Outlet. The trending of these two points can help identify if local or uniform changes are
occurring to the flow tubes.)

•

Trending – ProLink II has the ability to store a history of meter verification data points. This
history is displayed on the results graph. The rightmost data points are the most recent. This
history lets you see how your meter is trending over time, which can be an important way of
detecting meter problems before they become severe. You can view the graph of past results at
either the beginning or the end of the meter verification procedure. The graph is shown
automatically at the end. Click View Previous Test Data to view the graph at the beginning.

•

Data manipulation – You can manipulate the graphed data in various ways by double-clicking
the graph. When the graph configuration dialog is open, you can also export the graph in a
number of formats (including “to printer”) by clicking Export.

•

Detailed report form – At the end of a meter verification test, ProLink II displays a detailed
report of the test, which includes the same recommendations for pass/caution/abort results that
are found in Section 10.3.1. You have the options of printing the report or saving it to disk as
an HTML file.

More information about using ProLink II to perform meter verification can be found in the ProLink II
manual and in the on-line ProLink II help system.
Note: Historical data (e.g., previous test results or whether zero has changed) are stored on the
computer on which ProLink II is installed. If you perform meter verification on the same transmitter
from a different computer, from the display, or from a DeviceNet tool, the historical data will not be
visible.
10.4

Troubleshooting

Test metadata – ProLink II allows you to enter a large amount of metadata about each test so
that past tests can be audited easily. ProLink II will prompt you for this optional data during
the test.

Measurement Performance

•

Compensation

In addition to the Pass, Fail/Caution, and Abort result provided by the procedure, ProLink II provides
the following additional meter verification tools:

Performing meter validation
To perform meter validation:
1. Determine the meter factor(s) to use. You may set any combination of the mass flow, volume
flow, and density meter factors.
•

The mass flow meter factor affects only the value reported for mass flow.

•

The density meter factor affects only the value reported for density.

•

The volume flow meter factor affects only the value reported for volume flow.

Configuration and Use Manual

Defaults

Note that all three meter factors are independent:

Measurement Performance

Therefore, to adjust volume flow, you must set the meter factor for volume flow. Setting a
meter factor for mass flow and a meter factor for density will not produce the desired result.
The volume flow calculations are based on original mass flow and density values, before the
corresponding meter factors have been applied.
2. Calculate the meter factor as follows:
a. Sample the process fluid and record the process variable value reported by the flowmeter.
b. Measure the sample using an external standard.
c. Calculate the new meter factor using the following formula:
ExternalStandard
NewMeterFactor = ConfiguredMeterFactor × --------------------------------------------------------------------------------ActualFlowmeterMeasurement

If you are calculating the volume flow meter factor, note that proving volume in the field may
be expensive, and the procedure may be hazardous for some process fluids. Therefore, because
volume is inversely proportional to density, an alternative to direct sampling and measurement
is to calculate the volume flow meter factor from the density meter factor. This method
provides partial correction by adjusting for any portion of the total offset that is caused by
density measurement offset. Use this method only when a volume flow reference is not
available, but a density reference is available. To use this method:
a. Calculate the meter factor for density, using the preceding formula.
b. Calculate the volume flow meter factor from the density meter factor, as shown below:
1
MeterFactor Volume = ----------------------------------------------MeterFactor Density

Note: This equation is mathematically equivalent to the equation shown below. You may use
whichever equation you prefer.
Density Flowmeter
MeterFactor Volume = ConfiguredMeterFactor Density × ------------------------------------------------------Density ExternalStandard

3. Ensure that the meter factor is between 0.8 and 1.2, inclusive. If the calculated meter factor is
outside these limits, contact Micro Motion customer service.
4. Configure the meter factor in the transmitter. To configure meter factors:

•

Using ProLink II, see Figure B-2.

•

Using the display menus, see Figure B-6.

•

Using a DeviceNet tool, see Tables C-1, C-2, and C-3.

The flowmeter is installed and proved for the first time. The flowmeter
mass measurement is 250.27 lb; the reference device measurement is
250 lb. A mass flow meter factor is determined as follows:

One year later, the flowmeter is proved again. The flowmeter mass
measurement is 250.07 lb; the reference device measurement is
250.25 lb. A new mass flow meter factor is determined as follows:
250.25
MassFlowMeterFactor = 0.9989 × ------------------ = 0.9996

10.5

Performing zero calibration
Zeroing the flowmeter establishes the flowmeter’s point of reference when there is no flow. The meter
was zeroed at the factory, and should not require a field zero. However, you may wish to perform a
field zero to meet local requirements or to confirm the factory zero.
When you zero the flowmeter, you may need to adjust the zero time parameter. Zero time is the
amount of time the transmitter takes to determine its zero-flow reference point. The default zero time
is 20 seconds.
•

A long zero time may produce a more accurate zero reference but is more likely to result in a
zero failure. This is due to the increased possibility of noisy flow, which causes incorrect
calibration.

•

A short zero time is less likely to result in a zero failure but may produce a less accurate zero
reference.

Note: Do not zero the flowmeter if a high-severity alarm is active. Correct the problem, then zero the
flowmeter. You may zero the flowmeter if a low-severity alarm is active. See Section 7.5 for
information on viewing transmitter status and alarms.
If the zero procedure fails, two recovery functions are provided:
•

Restore prior zero, available only from the Calibration dialog box in ProLink II (see
Figure B-1), and only if you have not closed the Calibration window or disconnected from the
transmitter. Once you have closed the Calibration window or disconnected from the
transmitter, you can no longer restore the prior zero.

•

Restore factory zero, available via:
The display – see Figure B-7

ProLink II – see Figure B-1

A DeviceNet tool – use the Diagnostics Object (0x66), Instance 1, Service 0x52. For more
information, see the manual entitled Micro Motion Model 2400S Transmitters
for DeviceNet: Device Profile.

If desired, you can use one of these functions to return the meter to operation while you are
troubleshooting the cause of the zero failure (see Section 11.8).

Preparing for zero

To prepare for the zero procedure:
1. Apply power to the flowmeter. Allow the flowmeter to warm up for approximately 20 minutes.
2. Run the process fluid through the sensor until the sensor temperature reaches the normal
process operating temperature.
3. Close the shutoff valve downstream from the sensor.
4. Ensure that the sensor is completely filled with fluid.
5. Ensure that the process flow has completely stopped.

CAUTION
If fluid is flowing through the sensor during zero calibration, the calibration
may be inaccurate, resulting in inaccurate process measurement.
To improve the sensor zero calibration and measurement accuracy, ensure that
process flow through the sensor has completely stopped.

10.5.2

Zero procedure

To zero the flowmeter:
•

Using the zero button, see Figure 10-4.

•

Using the display menu, see Figure 10-5. For a complete illustration of the display zero menu,
see Figure B-7.

•

Measurement Performance

The calibrations that you choose must be performed without interruption, in the order listed here.
Note: Before performing the calibration, record your current calibration parameters. If you are using
ProLink II, you can do this by saving the current configuration to a file on the PC. If the calibration
fails, restore the known values.
You can calibrate for density with ProLink II or a DeviceNet tool.
10.6.1

Preparing for density calibration

Before beginning density calibration, review the requirements in this section.
Sensor requirements
During density calibration, the sensor must be completely filled with the calibration fluid, and flow
through the sensor must be at the lowest rate allowed by your application. This is usually
accomplished by closing the shutoff valve downstream from the sensor, then filling the sensor with
the appropriate fluid.
Density calibration fluids
D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-density) fluid. You
may use air and water. If you are calibrating a T-Series sensor, the D1 fluid must be air and the D2
fluid must be water.

CAUTION
For T-Series sensors, the D1 calibration must be performed on air and the D2
calibration must be performed on water.

For D3 density calibration, the D3 fluid must meet the following requirements:
•

Minimum density of 0.6 g/cm3

•

Minimum difference of 0.1 g/cm3 between the density of the D3 fluid and the density of water.
The density of the D3 fluid may be either greater or less than the density of water

For D4 density calibration, the D4 fluid must meet the following requirements:
•

Minimum density of 0.6 g/cm3

•

Minimum difference of 0.1 g/cm3 between the density of the D4 fluid and the density of the
D3 fluid. The density of the D4 fluid must be greater than the density of the D3 fluid

•

Minimum difference of 0.1 g/cm3 between the density of the D4 fluid and the density of water.
The density of the D4 fluid may be either greater or less than the density of water

To speak to a customer service representative, contact the Micro Motion customer service department.
Contact information is provided in Section 1.10.
Before contacting Micro Motion customer service, review the troubleshooting information and
procedures in this chapter, and have the results available for discussion with the technician.

11.4

Transmitter does not operate
If the transmitter is not receiving power, all three LEDs on the user interface will be off.
1. Check the DeviceNet connector (see Section 11.7.1).
2. Ensure that the network is providing sufficient power to the device.
If at least one LED is lit, perform all of the procedures in Section 11.7.
If the procedures do not indicate a problem with the electrical connections, contact the Micro Motion
customer service department.

11.5

Transmitter does not communicate
If the transmitter does not appear to be communicating, the wiring may be faulty or the
communications device may be incompatible. Check the wiring and the communication device. See
Chapter 4 for ProLink II and Pocket ProLink, or Chapter 5 for a DeviceNet tool.
If you are trying to communicate via the IrDA port, ensure that the port is enabled, that read-write
access is enabled, and that there is no active connection via the service port clips. See Section 8.10.6.

112

Micro Motion® Model 2400S Transmitters for DeviceNet™

Troubleshooting

1. Verify the DeviceNet node address and baud rate for the transmitter. If necessary, change their
values using the digital communications hardware switches on the user interface (see Sections
8.10.1 and 8.10.2), and retry the connection using the new digital communications parameters.

Compensation

If the transmitter is communicating via the service port but not via DeviceNet, if you are experiencing
intermittent DeviceNet communications, or if the transmitter appears to be operating normally but you
cannot establish a DeviceNet connection:

2. Check the DeviceNet cable and connector as described in Section 11.7.1.
3. A variety of network issues can cause communications problems (e.g., bus errors, bus traffic,
too many nodes, insufficient power, shield voltage problems, or flat cable shorts). Follow your
site’s standard procedures for diagnosing and correcting these problems.
11.6

The Model 2400S DN transmitter is compatible with all DeviceNet tools. Check that your DeviceNet
tool is correctly configured and can make a connection to other devices on the network.

WARNING
Removing the transmitter housing cover in explosive atmospheres while the
device is powered can subject the transmitter to environmental conditions
that can cause an explosion.
Before removing the transmitter housing cover in explosive atmospheres, be sure
to remove power from the device and wait five minutes.

Defaults

11.7.1

Checking the DeviceNet cable and connector

To check the DeviceNet cable and connector:
1. Follow appropriate procedures to ensure that the process of checking the DeviceNet cable and
connector does not interfere with existing measurement and control loops.
2. Disconnect the DeviceNet cable from the connector on the transmitter. See Figure 11-1.
Configuration and Use Manual

113

Troubleshooting

3. Visually inspect the cable and connector. Ensure that contact is good at both ends, that the pins
are not bent, the cable is not crimped, and the cable covering is intact.
4. Retry the connection using a different cable.
Figure 11-1 DeviceNet connector

11.7.2

Checking grounding

The sensor / transmitter assembly must be grounded. See your sensor installation manual for
grounding requirements and instructions.
11.8

Zero or calibration failure
If a zero or calibration procedure fails, the transmitter will send a status alarm indicating the cause of
failure. See Section 11.12 for specific remedies for status alarms indicating calibration failure.

11.9

Fault conditions
If a fault is reported, determine the exact nature of the fault by checking the status alarms (see
Section 7.6). Once you have identified the status alarm(s) associated with the fault condition, refer to
Section 11.12.
Some fault conditions can be corrected by cycling power to the transmitter. A power cycle can clear
the following:
•

Zero failure

•

Stopped internal totalizer

11.10 Simulation mode for process variables
Simulation allows you to define arbitrary values for mass flow, temperature, and density. Simulation
mode has several uses:

114

•

It can help determine if a problem is located in the transmitter or elsewhere in the system. For
example, signal oscillation or noise is a common occurrence. The source could be the PLC, the
meter, improper grounding, or a number of other factors. By setting up simulation to output a
flat signal, you can determine the point at which the noise is introduced.

•

It can be used to analyze system response or to tune the loop.
Micro Motion® Model 2400S Transmitters for DeviceNet™

Troubleshooting

•

All mass flow, temperature, or density values shown on the display or reported via digital
communications

•

The mass total and inventory values

•

All volume calculations and data, including reported values, volume total, and volume
inventory

•

All related values logged by Data Logger (a ProLink II utility)

Compensation

If simulation mode is active, the simulated values are stored in the same memory locations used for
process data from the sensor. Therefore, the simulated values will be used throughout transmitter
functioning. For example, simulation will affect:

Accordingly, do not enable simulation when your process cannot tolerate these effects, and be sure to
disable simulation when you have finished testing.

Simulation does not change any diagnostic values.
Simulation mode is available only via ProLink II. To set up simulation, refer to Figure B-3 and follow
the steps below.
1. Enable simulation mode.
2. For mass flow:
a. Specify the type of simulation you want: fixed value, sawtooth (triangular wave), or sine
wave.

Measurement Performance

Note: Unlike actual mass flow and density values, the simulated values are not
temperature-compensated.

b. Enter the required values.
•

If you specified fixed value simulation, enter a fixed value.

•

If you specified sawtooth or sine wave simulation, enter a minimum value, maximum
value, and wave period. Minimum and maximum values are entered in the current
measurement units; the wave period is entered in seconds.

To use simulation mode for problem location, enable simulation mode and check the signal at various
points between the transmitter and the receiving device.
Be sure to disable simulation when testing is complete.

Troubleshooting

3. Repeat Step 2 for temperature and density.

11.11 Transmitter LEDs
The user interface board includes three LEDs:
•

A status LED. See Table 7-5 for information on status LED behavior. If the status LED
indicates an alarm condition:
a. View the alarm code using the procedures described in Section 7.5.
b. Identify the alarm (see Section 11.12).
c. Correct the condition.

•

A module LED. See Table 7-3 for information on the behavior of the module LED and
suggestions on user response.

•

A network LED. See Table 7-4 for information on the behavior of the network LED. The
network LED indicates the state of the device on the network, and does not indicate device
status. Troubleshooting should focus on the network rather than the device.

11.12 Status alarms
Status alarm codes are reported on the LCD panel (for transmitters that have a display), and status
alarms can be viewed with ProLink II or a DeviceNet tool (see Section 7.6). All possible status alarms
are listed in Table 11-2, along with the ProLink II message, possible causes, and suggested remedies.
You may find it useful to acknowledge all alarms before beginning the troubleshooting procedures.

Compensation

Symptom

Troubleshooting

If slug flow occurs:
•

Check the process for cavitation, flashing, or leaks.

•

Change the sensor orientation.

•

Monitor density.

•

If desired, enter new slug flow limits (see Section 8.7).

•

Raising the low slug flow limit or lowering the high slug flow limit will increase the
possibility of slug flow conditions.

Lowering the low slug flow limit or raising the high slug flow limit will decrease the
possibility of slug flow conditions.

If desired, increase slug duration (see Section 8.7).

11.15 Checking the sensor tubes
Corrosion, erosion, or damage to the sensor tubes can affect process measurement. To check for these
conditions, perform the meter verification procedure. See Chapter 10.
11.16 Checking the flow measurement configuration
Using an incorrect flow measurement unit can cause the transmitter to report unexpected process
variable values, with unpredictable effects on the process. Make sure that the configured flow
measurement unit is correct. Check the abbreviations; for example, g/min represents grams per
minute, not gallons per minute. See Section 6.3.
11.17 Checking the characterization
A transmitter that is incorrectly characterized for its sensor might report inaccurate process variable
values. Both the K1 and Flow Cal (FCF) values must be appropriate for the sensor. If these values are
incorrect, the sensor may not drive correctly or may send inaccurate process data.
If you discover that any of the characterization data are wrong, perform a complete characterization.
See Section 6.2.
11.18 Checking the calibration
Improper calibration can cause the transmitter to report unexpected process variable values. If the
transmitter appears to be operating correctly but sends unexpected process variable values, an
improper calibration may be the cause.
Micro Motion calibrates every transmitter at the factory. Therefore, you should suspect improper
calibration only if the transmitter has been calibrated after it was shipped from the factory. Before
performing a calibration, consider meter validation or meter verification and select the appropriate
procedure (see Section 10.2). Contact Micro Motion customer service for assistance.
11.19 Checking the test points
Some status alarms that indicate a sensor failure or overrange condition can be caused by problems
other than a failed sensor. You can diagnose sensor failure or overrange status alarms by checking the
flowmeter test points. The test points include left and right pickoff voltages, drive gain, and tube

Troubleshooting

11.19.3

Drive gain problems

Problems with drive gain can appear in several different forms:
•

Saturated or excessive (near 100%) drive gain

•

Erratic drive gain (e.g., rapid shifting from positive to negative)

•

Negative drive gain

See Table 11-6 for a list of possible problems and remedies.
Table 11-6 Drive gain problems, causes, and remedies
Cause

Possible remedy

Excessive slug flow

• See Section 11.14.

Cavitation or flashing

• Increase inlet or back pressure at the sensor.
• If a pump is located upstream from the sensor, increase the distance
between the pump and sensor.

Plugged flow tube

• Purge the flow tubes.

Mechanical binding of sensor tubes

• Ensure sensor tubes are free to vibrate. Possible problems include:
- Pipe stress. Check for pipe stress and eliminate if present.
- Lateral tube shift due to hammer effect. If this is a possibility,
contact Micro Motion. See Section 11.3.
- Warped tubes caused by overpressurization. If this is a possibility,
contact Micro Motion.

Incorrect sensor type configured

• Verify sensor type configuration, then verify sensor characterization.

Low pickoff voltage can be caused by several problems. See Table 11-7.
Table 11-7 Low pickoff voltage causes and remedies
Cause

Possible remedy

Slug flow

• See Section 11.14.

No tube vibration in sensor

• Check for plugging.

Moisture in the sensor electronics

• Eliminate the moisture in the sensor electronics.

Damaged sensor

• Ensure sensor is free to vibrate (no mechanical binding). Possible
problems include:
- Pipe stress. Check for pipe stress and eliminate if present.
- Lateral tube shift due to hammer effect. If this is a possibility,
contact Micro Motion. See Section 11.3.
- Warped tubes caused by overpressurization. If this is a possibility,

Micro Motion® Model 2400S Transmitters for DeviceNet™

Troubleshooting

11.20 Checking sensor circuitry

•

Inspecting the cable that connects the transmitter to the sensor

•

Measuring the resistances of the sensor's pin pairs and RTDs

•

Ensuring that the circuits are not shorted to each other or to the sensor case

Compensation

Problems with sensor circuitry can cause several alarms, including sensor failure and a variety of
out-of-range conditions. Testing involves:

Note: To check the sensor circuitry, you must remove the transmitter from the sensor. Before
performing this test, ensure that all other applicable diagnostics have been performed. Diagnostic
capabilities of the Model 2400S transmitter have been greatly enhanced, and may provide more useful
information than these tests.
1. Follow appropriate procedures to ensure that the process of checking the sensor circuitry does
not interfere with existing measurement and control loops.
Measurement Performance

2. Disconnect the DeviceNet cable from the DeviceNet connector on the Model 2400S DN
transmitter.
3. If the transmitter is in a hazardous environment, wait five minutes.
4. Check the sensor cable and sensor connection:
a. Referring to Figure 11-2, loosen the four captive transmitter housing cover screws and
remove the transmitter housing cover.
b. Loosen the two captive user interface screws.
c. Gently lift the user interface module, disengaging it from the connector on the transmitter.
d. Two captive screws (2.5 mm hex head) hold the transmitter in the housing. Loosen the
screws and gently lift the transmitter away from the housing. Allow the transmitter to hang
by the cable.
e. Check the cable for any signs of damage.
f.

Troubleshooting

Ensure that the cable is fully plugged in and making a good connection. If it is not, reseat
the cable, reassemble the transmitter and sensor, and check operation.

6. Using a digital multimeter (DMM), check the sensor internal resistances for each flowmeter
circuit. Table 11-8 defines the flowmeter circuits and the resistance range for each. Refer to
Figure 11-4 to identify the feedthrough pins. For each circuit, place the DMM leads on the pin
pairs and record the values.

In this test:
•

There should be no open circuits, i.e., no infinite resistance readings.

•

Nominal resistance values vary 40% per 100 °C. However, confirming an open or shorted
circuit is more important than any slight deviation from the resistance values shown here.

•

The LPO and RPO circuit readings should be the same or very close (± 10%).

•

The readings across pin pairs should be steady.

•

Actual resistance values depend on the sensor model and date of manufacture. Contact
Micro Motion for more detailed data.

Troubleshooting

Note: In order to access all feedthrough pins, you may need to remove the clamp and rotate the
transmitter to a different position.

If a problem appears, or if any resistance is out of range, contact Micro Motion (see
Section 11.3).

Table 11-9

Sensor and cable short to case causes and remedies

Cause

Possible remedy

Moisture inside the transmitter housing

• Make sure that the transmitter housing is dry and no corrosion is
present.
• Contact Micro Motion. See Section 11.3.

Internally shorted feedthrough (sealed passage
for wiring from sensor to transmitter)

• Contact Micro Motion. See Section 11.3.

Faulty cable connecting sensor to transmitter

• Visually inspect the cable for damage. To replace cable, contact
Micro Motion. See Section 11.3.

To return to normal operation:
1. Follow appropriate procedures to ensure that reconnecting the transmitter does not interfere
with existing measurement and control loops.
2. Reach inside the transmitter housing and install the transmitter’s sensor connection onto the
feedthrough:
a. Rotate the connector until it engages the pins.

Measurement Performance

Liquid or moisture inside the sensor case

Compensation

With the DMM set to its highest range, there should be infinite resistance on each lead. If there
is any resistance at all, there is a short to case or a short between pins. See Table 11-9 for
possible causes and solutions. If the problem is not resolved, contact Micro Motion (see
Section 11.3).

b. Push down until the connector shoulder is flush with the feedthrough notch.
c. Replace the snap clip by sliding the clip tab over the connector shoulder (see instruction
label).
3. Replace the transmitter in the transmitter housing, and tighten the screws.

5. Tighten the user interface screws.
6. Replace the transmitter housing cover on the user interface module, and tighten the screws.
7. Reinsert the DeviceNet cable into the DeviceNet connector on the transmitter.
